How to Check WordPress Website Performance & Ways to Improve it

Your WordPress site might look great, but how fast does it load? And is it running as well as it should? Website performance matters more than most people think. A slow site can push visitors away, hurt your search rankings, and even cost you sales or leads. So regularly checking it is important to maintain a consistent flow of visitors.

And checking the speed of your WordPress site isn’t something very complex. There are many tools that can help you check how your site is doing and improve it without much hassle.

So, in this blog, we’ll discuss how to check your website performance, what to look for, and easy ways to make WordPress websites faster. Let’s get started!

Factors Affecting WordPress Website Performance

Many things impact the speed and overall performance of your WordPress website. Identifying and optimizing these areas can keep the user experience fast and smooth.

Unoptimized Images

Large image files increase loading times of the website. It does increase the page weight. The speed and the bandwidth are taken away by high-res images. Image Optimization improves the performance using appropriate formats and different types of compressions.

Slow Hosting Provider

Unreliable hosting leads to poorer server response times and high downtime. Shared hosting plans will usually not manage heavy traffic, resulting in slow speed benefits to the site. Choosing a reliable hosting provider with optimized servers enhances performance.

Excessive HTTP Requests

Each element on a webpage, including images, scripts, and stylesheets, generates HTTP requests. Too many requests increase page load time and delay content display. Reducing unnecessary elements and combining resources can improve speed.

Unused Plugins and Themes

Installing too many plugins or using heavy themes can slow down WordPress. Some plugins add excessive scripts and database queries, reducing performance. Removing unused plugins and choosing lightweight themes helps optimize speed.

Large Database Size

WordPress databases collect unnecessary data over time. This includes revisions, spam comments, and transients. When the database isn’t optimized, queries take longer to execute. This slowdown affects overall website performance. Regular cleaning and optimization boost database efficiency.

Lack of Caching Mechanisms

Without caching, WordPress dynamically loads content for every request, increasing server load. Caching plugins store static versions of pages, reducing processing time. You can clear cache in WordPress to improve loading speed and reduce resource consumption.

Too Many External Scripts

Third-party scripts like ads, fonts, and tracking codes add extra load time. These scripts require external requests, which slow down page rendering. Minimizing or optimizing external resources can help maintain website speed.

No Content Delivery Network (CDN)

If CDN is not used, the website has to pull content from a single server. But if a CDN is used in WordPress, your content will be stored on multiple servers globally. It will let visitors see your site faster, no matter their location.

By addressing these factors, you can improve your WordPress website’s performance. Regular WordPress uptime monitoring, optimization, and maintenance ensure your site remains robust and optimal for users.

Key Metrics to Evaluate WordPress Website Performance

When you check your WordPress website’s performance, it includes tracking metrics that indicate speed, responsiveness, and user experience. Here are the key performance metrics you should evaluate:

Page Load Time

This metric measures how long a webpage takes to fully load. Slow loading speeds lead to higher bounce rates. This creates a poor experience for visitors. You can boost performance by optimizing images and files. Implementing proper caching helps too. Removing unneeded scripts also improves load times.

Time to First Byte (TTFB)

TTFB (Time To First Byte) measures how quickly a server responds. It tracks when the browser gets the first data byte. High TTFB often reveals server-side issues. This may indicate inefficient processing. It can also signal poor hosting quality. Using a better hosting provider and caching can reduce server response times.

Largest Contentful Paint (LCP)

LCP measures how quickly the largest visible content loads on a webpage. A slow LCP negatively affects user experience and search engine rankings. Optimizing images, reducing render-blocking scripts, and using a CDN help improve LCP.

First Input Delay (FID)

FID evaluates the time taken for a website to respond to a user’s first interaction. A long delay means users experience lag when clicking buttons or links. Minimizing JavaScript execution and enabling browser caching can enhance responsiveness.

Cumulative Layout Shift (CLS)

CLS measures the visual stability of a webpage by tracking unexpected layout shifts. Pages with shifting elements create a frustrating experience for users. Defining dimensions for media elements and avoiding dynamically injected content improves CLS.

Database Query Time

This metric measures the time taken to execute database queries and retrieve content. A slow query time results from bloated databases or inefficient indexing. Regularly optimizing and cleaning up the database enhances query performance.

Requests Per Second (RPS)

RPS determines how many requests a server can handle within a second. A low RPS suggests server overload, affecting website availability and speed. Scalable hosting, load balancing, and optimal queries can further improve the handling of requests.

Regularly checking performance metrics keeps your WordPress site fast and user-friendly. Tools like Google PageSpeed Insights, GTmetrix, and Pingdom help track these key metrics. They provide actionable insights to optimize your site effectively.

Best Practices to Improve WordPress Website Performance

Your site’s performance analysis is complete. Now it’s time for optimization. Follow these proven best practices. They’ll boost your WordPress speed significantly. Your site will become more responsive. Overall efficiency will improve too.

• Use a Lightweight and Fast Theme:  Themes that have many features can make your website slower. Prefer a lightweight theme optimized for speed, such as GeneratePress, Astra, or Neve. Do not use themes with unnecessary animations, widgets, and scripts.
• Optimize Images for Faster Loading: Large images are a top cause of slow-loading websites. Use plugins like TinyPNG, Imagify, or ShortPixel to optimize them. These tools reduce file sizes while keeping quality sharp. Also, enable lazy loading for images. This ensures they only load when visible on screen.
• Minify CSS, JavaScript, and HTML: Minification streamlines your code by removing unnecessary elements. It eliminates extra spaces, comments, and redundant characters. This process significantly reduces file sizes. For WordPress sites, use plugins like Autoptimize or WP Rocket. These tools effectively minify CSS, JavaScript, and HTML files. The result is faster loading times and improved performance.
• Enable Caching for Faster Page Loads: Caching stores static versions of your website to minimize server requests. This reduces server load and speeds up page delivery. For optimal results, install caching plugins like WP Rocket, W3 Total Cache, or WP Super Cache. These solutions handle both page caching and browser caching efficiently.
• Use Faster and Reliable Web Hosting: While choosing a hosting provider, the performance should be a priority. You may be served well with a managed WordPress service from WP Engine or SiteGround when needing a healthy speed, uptime, and security all together.
• Limit Plugin Usage and Remove Unused Plugins: Using too many plugins slows down your website. Each active plugin adds to the loading time. Always deactivate plugins you’re not currently using. For better efficiency, consider multi-purpose plugins. Options like Jetpack or Rank Math combine multiple features.

Utilizing these best practices can enhance the speed of your WordPress and improve the experience for users.
